Siemens EQ6 300 water puddle under machine

Hello all. I have the problem that there is a big puddle of water under the machine. I hope you can see from my picture where the water is probably coming from. However, when I remove the side panels I can't see any water on the walls or hoses. Do you know what is sitting above this cover?

This sits directly above the leak. Everything else about the components is dry.

Hello the white plastic part is an expansion chamber.
There you will just have to search where the water comes from. Under the KVA to 90% from the water tank to the brewing unit - bridge the water sensor with a magnet and with hose from flowmeter (from the aquarist store) externally produce the water circuit.
Good luck.

Okay I will try. I have looked at the whole thing before with the side and rear flap open but it is not dripping out or down anywhere. But still like the first picture there is a leak. Maybe someone knows the problem....

If the puddle of water forms when the machine is switched off, the water pump is most likely defective; if this is the case during operation, there is more likely a blockage, e.g. calcification, in which case intensive descaling should be carried out.
